Objective To study the similarities and differences of information needs between cancer patients treated with radiotherapy and chemotherapy, analyze the causes for cancer patients' different choices, and provide reasonable and disease-related information for cancer patients. Methods A total of 102 and 119 cancer patients treated with radiotherapy and chemotherapy relatively were asked to complete the questionnaire (IPQCP+2) and two questions about the total information capacity and content requirements. Results Two groups had different needs of therapeutic information and treatment in IPQCP. Cancer patients treated with chemotherapy needed more widely-ranged information than patients underwent radio-therapy. Conclusions Most of cancer patients treated with radiotherapy and chemotherapy need to be informed of disease-related information, among which the content of therapeutic information and total information is relative to the treatment. Nurses should provide disease-related medical information based on their different needs, as to improve the life quality of cancer patients.

Objective To apply failure mode and effect analysis (FMEA) to reduce nursing risk of peripherally inserted central catheter (PICC).Methods 100 patients with PICC in central hospital of Minxing District of Shanghai were named as the experimental group,failure mode and effect analysis were performed in this group to obtain the value of risk priority number (PRN) and array them according to the RPN value to work out improved plan systematically and put it into practice to guide the clinical operation and nursing care.98 PICC patients in Xinzhuang health service center and Tumor Hospital of Minhang district were set as the control group,which were subjected to traditional nursing.All statistical analysis were done by SPSS 11.0 software package,the differences of the incidence of PICC-related nursing risk between the two groups due to the implementation of FMEA was analyzed by X2 test.Results Application of FMEA could reduce the nursing risk of PICC,After the application of FMEA,the incidence of PICC-related complications such as focal or systemic infection,puncture site oozing and bleeding,skin allergies,mechanical phlebitis,too deeply placed catheter,catheterization into cervical veins and reflexed into axillary vein,catheter occlusion,catheter migration,difficult removal of catheter,puncture failure in the experimental group decreased obviously,the differences had statistical meaning.Conclusions The application of failure mode and effects analysis can reduce the nursing risk of PICC,decrease medical disputes,alleviate the suffering of patients,reduce medical costs caused by PICC-related complications,and improve the satisfaction degree of patients and the quality of nursing care.

Objective To study the effect of theory and practice integrated teaching in der-matology education and to explore the effective teaching means. Methods 53 five-year program stu-dents of Grade 2008 who major in clinical medicine were subjects. 26 students involved in the inves-tigation were taught with theory and practice integrated teaching. 27 students were taught with tradi-tional teaching method. In order to understand the teaching effect, we use questionnaire in experimental group and carry on comprehensive evaluation in both group at the end of the course . Descriptive statistics method was applied to describe the experimental group students' evaluation of the theory-practice integration teaching methods; The results of the two groups of students were applied t-test to perform statistical analysis and the difference was statistically significant (P<0.05). Results The stu-dents in the experimental group hold positive attitudes to theory and practice integrated teaching. 25 students (96.2%) in experimental group confirmed the necessity of it and considered that it could improve the communication skill. 24 students (92.3% ) confirmed it attractive and considered that it could improve the learning interest and capacity of clinical practice. 23 students (88.5% ) thought active learning and learning efficiency were promoted and theoretical knowledge was consolidated. 22 students (84.6%) considered that it could promote the comprehension of dermatology. Besides, the ex-perimental group students' medical ethics, theory and skills were significantly higher than those of the control group (P<0.05). Conclusion Theory and practice integrated teaching in dermatology edu-cation is effective. It can promote students' learning interest and initiative. It can improve the profes-sional quality of students and comprehensive quality of teachers.

Telomere maintenance plays a critical role in cancer progression.Approximately 85% human cancer cells maintain their telomere length through activation of telomerase.Other 15%of cancers maintain telomere length independently of telom-erase by alternative lengthening of telomeres (ALT)pathway. Both events are equally important for telomere length mainte-nance of cancer cells.Human telomere consists of a series of G rich DNA sequences,which could form G-quadruplex.The for-mation of this structure can block the extension of telomeres by telomerase or ALT,resulting in cancer cell death.Thereby,G-quadruplex has been one of the focuses of anticancer therapy in recent years.This review focuses on the latest progress of G-quadruplex stabilizers.

BACKGROUND:The kidney tissues easily affected exercise ischemia reperfusion, increased free radicals and inflammation, resulted in abnormal renal function after acute exercise. OBJECTIVE:To observe the influence of Blackcurrant Extract on the structure of kidney and expression of tumor necrosis factor-α and nuclear factor-κB at 24 hours after exhaustiveexercise. METHODS:A total of 30 male Wistar rats were randomly divided into three groups (n=10). Rats in the Blackcurrant Extract group were intragastricaly administered 0.44 g/kg Blackcurrant Extract. Rats in the quietness control group and 24-hour exhaustive exercise group were intragastricaly given an equal volume of distiled water for 6 consecutive weeks. Rats in the 24-hour exhaustive exercise group and Blackcurrant Extract group received no swimming motion until exhaustion fatigue after final intragastric administration. Twenty-four hours later, samples were obtained. Kidney tissue morphology and ultrastructure were observed by electron microscopy and light microscopy. Protein expression of tumor necrosis factor-α and nuclear factor-κB was detected using immunohistochemistry. Tumor necrosis factor-αmRNA and nuclear factor-κB mRNA expression was detected using RT-PCR. RESULTS AND CONCLUSION:Compared with the quietness control group, tumor necrosis factor-α protein and nuclear factor-κB protein expression in the kidney was higher in the 24-hour exhaustive exercise group, and tumor necrosis factor-α mRNA and nuclear factor-κB mRNA expression was significantly increased (P < 0.01). Compared with the 24-hour exhaustive exercise group, tumor necrosis factor-α protein and nuclear factor-κB protein expression was lower in the Blackcurrant Extract group, and nuclear factor-κB mRNA expression was significantly decreased (P < 0.05); tumor necrosis factor-α mRNA expression was significantly reduced (P < 0.01). Kidney in the 24-hour exhaustive exercise group showed obvious morphological changes and ultrastructural damage. The structure of the kidney in the Blackcurrant Extract group tended to be normal. Results suggested that Blackcurrant Extract can repair the kidney tissue injury, reduce the expression of inflammatory factors, and prevent inflammatory damage in the kidney at 24 hours after exhaustive exercise.
